An alternative that reduces losses is to have a series parallel setup for the panels, connect to the controller using normal solar...

Use the panels and MPPT to charge the lithium battery. Use the PWM , set for a charge voltage of 13.8 volts, between lithium as an...

You may have the inverter connected to the controller output. The inverter should be connected direct to the battery via a fuse at the...

ALL chargers negative connect to the negative buss, connect the negative from the DC to DC to the negative buss, not the battery...

All charger negatives connect to the negative buss bar, or P-, not the battery. The alternator charger is negative connected to...

Correct. The cell interconnections can partially fail and overheat. This has happened of numerous occasions with extensive burn marks...

Please explain which current source, In excess of 15 amps, exists in a two string set up?

That's 15 amps per panel or a string of those panels. With two strings in parallel, technically no series fuse is needed, unless local...

The better quality inverters have a lower standby power consumption and may also have a power save mode where the Inverter drops to a...

Yes.

Disconnect the batteries from each other and the chargers. Test the voltage with a meter , and test each independently for charging and...

That's strange, the smart shunt is normally resionable accurate. Have a look at the series 1A fuse in the sence cable, this may have a...

This is typical of BMS shutdown on one of your series batteries. Since the controller cannot respond fast enough the voltage spikes...

Can the controller take the series voltage? What is the Voc of the panel? If the Voc is 37 volts, 5 in series, gives 185 volts. Cold...

Meter may not be calibrated or low battery in the meter.

I think you are in the UK Use the solar to charge the house, leasure lithium battery. Connect this between lithium and starter battery...

PWM controllers typically have poor charging profile and tend to kill batteries. Add this factor to an ageing lead battery and you...

Your existing camper system will have 12v batteries so if the two AGM are Installed as a replacement /addition in their place, then...

The PWM only allows current flow from the panel , thus with a typical charging volts of 13.5 and panel current of 13 amps, that's 175...

Three panels can be connected in parallel or series to the controller. If more than two in parallel, technically fuses are needed on...
